Conservation status: CNPS 1B.1

Santa rosa island dudleya is a rare (CNPS 1B.1) California native perennial found in northern Channel Islands on Santa Rosa Island in coastal bluffs at elevations of 3 to 90 meters. Flowering from April to June, this plant produces white to pale yellow flowers in compact clusters above small spherical rosettes. Growing with short stems 1 to 2 centimeters tall and 5 to 20 millimeters wide, it forms dense, low-growing clusters. Its succulent leaves are bluish-green, typically more than 15 per rosette, each 1 to 3.5 centimeters long and 2 to 7 millimeters wide, creating a distinctive compact and glaucous appearance. The plant forms tight, rounded rosettes rarely exceeding 4 centimeters in width, adapted to the harsh coastal environment of its island habitat.
